dles; thereof in section and showing a gripped wire in section'the said wire being sectloned on the line4+4 of Figure 1.

Referring now more particularly to the drawing wherein like numeralslof reference' indicate corresponding parts throughoutthe several views,the numerals 1 and indicatethe two gripping jaws of the present wire gripping device, which jaws as shown, are of elongated substantially recj tangular contour and are relatively fiat as shown in Figure 4. These jaws when in operative position have two longitudinal edges in opposed relationand these opposed edges haveformed therein the grooves 3 in 65 which the wire 4 positions.

Each of theljaws l and 2 has formed integral therewith a pair of pin members 5 which are positioned upon opposite faces thereof and are longitudinally spaced as shown sothat each is adjacentone end of the jaw by which it is carried. Each of thesepins hasits outer end reduced as indicated at (land these outer end portions are w transversely apertured forjthe reception of? a cotter key or other holding element '7.

Y The gripping device has two handle mem berswhich are indicated bythenumerals "3 and 9 and each of these handle members has; a, straight rear portion 10 and a curved l forward portion 11. Each of thehandle members 81 and 9 receives through anaperture in the end of the curvedportion thereof the pin 5 of a jaw member which is nearest the forward end of the jaw, the forward end of eachnjaw being indicated by the rounded corner 12. i i p I Thehandles as shown, are "also placed on opposite sidesrof the jawsland one of the second, aperture tlierethrough at a point substantially midway of thecurved portion 11, for the reception of the pin member 5 nextto the one to which the curved forward f end thereof is attached, as illustrated in Figure 2. "The other handle 9 which is upon the opposite sideof the jaws 1 and 2 fromthehandle 8, while pivotally attached to the pin 5 which isnearest the forward f its outer reduced portion 6, which is inter-' posed between the adjacent handle member and the cotter key which retains the handles in position. The washer which is mounted on that pin 5 over which the curved portion of the handle 9 passes, is of greater diam eter than the other washers as shown in Figure 4 and this washer is indicated by the numeral 14. In addition to being of great er diameter than the washers 13 the washer 14. has its inner edge rounded or baffled as at 15 so as to act to guide the handle 9 to position 011 the adjacent pin 5 when the handle is swung into place.

The free ends of the straight portions 10 of the handles are notched upon their outer edges to form the outwardly directed hooks 16 so that a pair of links 17 may be readily connected therewith for attachment to a pull cable or rope through the medium of the common connecting link 18.

In the operation of the present wire gripping device, the wire 4 is placed in position between the jawsl and 2 by swinging the handle 9 forwardly on its pivot pin 5 which passes through the free end of the curved portion thereof, so that it will not extend across the adjacent grooved edges ofthe jaws as it is shown in Figure 1 but will be in the position-in which it is shown in Figure 3'. In this position it will be readily seen that the jaws are entirely free of any connection upon one side and the wire may then lie-easily laid therebetween to rest upon the underlying curved portion of the handle 8 which is pivotally permanently attached to both aws. back and the two handles gripped to be swung together the inner edge of the curved portion of the handle 9 will cam across the rear pin 5 of the jaw 1 and will thus cause the jaws to be firmly forced together as the handles are gripped. IVhile, ofcourse, the gripping device may be used in the hand by grasping the two handles 8 and 9, it is also designed to have a pull chain or line attached thereto through the medium of the link 18 to which the two links 17 are connected. v

These two links 17 as previously described are engaged behind the hooked out-turned end portions of the ends 16 of the handles and being connected together upon the longitudinal center of the gripping" device they will act to draw the handles inwardly when a pull is applied to the link 18 by which they'are joined'together.
